from psi?
1 psi = 2.31 feet of water or 1 ft of water = 0.43 psi
Or (what I suspect you mean) if you want the head loss in ft of water per 100' of tube or pipe at a specified flowrate, you'd look it up in a table -- See Burnham's Heating Helper for example (Google their site for it) or Cameron Hydraulic Data, or Thomas Glover's Pocket Ref (available here -- see the Books & More section -- for purchase. Elbows, tees, valves checks, etc. are converted to an equivalent length of pipe.0 -
and dont forget..
the water temp (and viscosity if you add anti-freeze)
just buy ziggis software, (hydronicspros.com), it's so much easier - not to mention less error prone
i really got to start getting commission for this
